Table 9 provides information for interface frequency limits. For more details about clocks characteristics,
Table 10 shows the fusebox supply current parameters.
1 In read mode, FUSE_VDD should be floated or grounded.
2 Fuses might be inadvertently blown if written to while the voltage is below the minimum.

CKIL Frequency1
1 CKIL must be driven by an external clock source to ensure proper start-up and operation of the device. CKIL is needed to clock
the internal reset synchronizer, the watchdog, and the real-time clock.

CKIH Frequency2
2 DPTC functionality, specifically the voltage/frequency relation table, is dependent on CKIH frequency. At the time of publication,
standard tables used by Freescale OSs provided for a CKIH frequency of 26 MHz only. Any deviation from this frequency
requires an update to the OS. For more details, refer to the particular OS user's guide documentation. DPTC/DVFS are not
supported for fARM
≤ 400MHz.
